No! Pput them where you want them, as long as they all stay together!

After the 'install' there will be a 'default profile' made in the C:\Documents and Settings\<users-name>\Application Data\Thunderbird folder in WinXP. I'm not sure of the location in W2K and Win98.

You can add profile(s) by adding a -P to the end of the path name for the TB execute file.
Use Start|Run and type or paste your path too TB.
Example: C:\Mozilla\thunderbird-mail\thunderbird\thunderbird.exe -P
you location will be different.
